Filtered storage containers for hazardous waste, such as radioactive waste, more particularly plutonium in the form of oxides and salts, are made of stainless steel and include lids which are retained by retaining rings that utilize bayonet or ratchet closures that cooperate with rims that are integral with cans to hold the lids in place. Sealing arrangements are provided that each include an O-ring of a circular cross section which seals radially between the lid and rim, as well as a seal of cruciform cross section, which seal provides compression sealing between the lid and an annular shelf within the rim upon locking the retaining ring to the rim with the bayonet or ratchet fitting.

A closure includes an overcap having an annular skirt, and an annular wall extending inwardly from the skirt. A lid is carried by the overcap radially within the annular skirt, and includes a hub, and an annular margin extending radially outwardly with respect to the hub, and having upper and lower surfaces. An annular container seal extends circumferentially continuously around the annular margin. One or more vents may extend through the annular margin between the upper and lower surfaces thereof at one or more discrete circumferential locations radially inward with respect to the container seal. One or more vent seals may be disposed at the one or more vents between the lid and the overcap.

A food preparation jar. The jar has a jar that accepts a lid. The lid having grooves inside to couple with the grooves on the upper portion of the jar. The lid further having a sealing ring that provides a secure and air-tight seal when the jar is heated and cooled.

The invention relates to lids for beverage containers and related methods, for example, a lid to fit within the screw on compression assembly found on standard canning jars to adapt the container to improve a user's ability to consume liquids directly from the vessel. Lids according to certain embodiments of the invention can be used with a wide range of containers like jars, so that the containers can be conveniently used to consume a beverage while avoiding spilling and facilitating extended use and recycling of the containers.

A seal releasing lid assembly includes a lid configured for coupling across a container opening of a container. The lid includes a lid surface and a lid wall extending from the lid surface. The lid wall includes a lid edge and a slidable coupling surface between the lid edge and the lid surface. The assembly includes a retaining and releasing ring configured for coupling with the container and with the lid. The retaining and releasing ring includes a ring flange and a release ridge. A ring wall extends from the ring flange to the release ridge. The retaining and releasing ring includes decoupling and release ready configurations. In the decoupling configuration the release ridge is slidably coupled along the lid wall. In the release ready configuration the release ridge is seated beneath the lid edge and slidably disengaged from the lid wall.

Beverages such as beer and soda which contain carbon dioxide or other gases may degrade in quality when subjected to atmospheric pressure, oxygen, and/or light. It may be desirable to store such beverages in containers which prevent exposure to these conditions. An aluminum can is one such container but is associated with the problem of resealing the can after breaking the seal. The described utilities provide for resealing, pressurizing, and/or dispensing from an aluminum can or similar beverage container.

A package seal for sealing engagement between a closure and a container, and including an elastomeric seal ring with a sealing portion, and a plastic projection coupled to the seal ring.

A closure assembly comprising a two-part closure having a metal panel or disc (2) and a ring (3), and a container such as a glass jar (20). The ring (3) is substantially cylindrical with an axially upwardly extending sidewall and has a radially inwardly extending lower edge. The jar (20) terminates in a radially outwardly extending beaded rim (16) and the disc (2) has a curled circumference (8) such that this curl (8) co-operates with the beaded rim (16) of the container to provide a primary seal. In one example, in a metal ring (3), the lower edge is curled with equally spaced lugs (13) on the skirt wall. In a plastic ring, the upper rim feature may be omitted.
